BUSHING STRUCTURE Filed June 25, 1928 2 Sheets-Sheet 2 Patented June i 7, 1932 UNITED STATES PATENT OFFICE HENRY SCHWARTZ, OF CHICAGO, ILLINOIS, ASSIGNOB TO BARREL FITTING AND SEAL CORPORATION OF AMERICA, OF CHICAGO, ILLINOIS, A CORPORATION OF vILLINOIS BUSHING STRUCTURE Application med .Tune 25, 1928. Serial No. 287,981.

This invention relates to a bushing structure and a sealing means therefor and has special reference to a structure such as is used as a bung for metallic barrels and other containers usually employed in storing or shipping oils or other liquids or semi-liquids.

More, particularly, this invention relates to a bung or plug which is so constructed and arranged as to effectively revent a leakage of the liquid or semi-liquid rom the container during the shipping or storage thereof and means for preventing access to the bun or plug in order to guard against an unaut orized opening of the barrel or container without such openingbeing detected.

In the embodiments illustrated and hereinafter described in this application, the bung is cast or otherwise formed With the usual tool engaging formations on the outer face thereof and is externally threaded adjacent vthe inner face thereof to engage an internally threaded bushing of the -container or barrel. The means for preventing access to the liquid in the barrel or the container without such access being detected comprises a. lug preferably formed integrally with the bung or plug, the lug having a weakened portion prefer# ably at the point of intersection with the bung in order that an unauthorized displacement of the bung will break the lug at the weakened portion. When it is`noted that the lug has been thus broken oii, the purchaser or user will have due notice that this container has been tampered with.

In addition to the above-noted construction,

a tag or seal is assembled together with the lug as a further indication, when displaced,

that the barrel has been tampered with. A

- f tag of this nature is usually provided on containers for oil and` other substances for denoting the quality thereof together Withthe shippers number and such other information as the reliner should desire to have placed thereon. It is apparent that the middle man -5 or jobber has an opportunity to substitute a tag denoting a grade of oil of higher quality for the tag originally placed thereon by the reiner and thus defraud the dealer and ultimate consumer should the latter -not be given due notice of such tampering. The present' invention contemplates preventing this prac*- tice.

Other objects and advantages will hereinafter be described and for a better understanding of the nature and characteristics and scope of this invention, reference may be now had to the following description and accompanying drawings; in which latter:

eferring to the drawings, and more particularly to Figs. 1 to 3, inclusive, thereof, a barrel head or supporting wall 10 of a container is shown and is preferably formed of sheet steel. A collar portion 11 having a flange 11a extending at substantially right angles thereto is preferably formed integrally with the head 10 and projects outwardly vfrom the interior of the barrel or the container to form a socket.

The side walls or collar 11 ofthe socket are preferably polygonally shaped and receive therein the main body portion 12 of a similar 100 peripheral contour. Although it is preferable to provide a polygonally shaped socket in which to contain the main body portion 12, it is (to be'understood that any outwardly extending socket of any particular contour may be employed, although it is preferable that the socket have a non-circular peripheral contour in Order to prevent the 'main body portion 12 from turning therein. The main body portion 12 is preferably formed of an internally threaded casting or Astamping which may be made of malleable-iron or analogous Substances.

In theparticular construction, shown in the various modifications of thisl invention, the edges or collar portion 11 of the socket are tapered, the taper converging rearwardly or inwardly from the outer surface of the container towards the inside side of the container; that is, the outer diameter at the bottom of the main body portion 12 is smaller than the outer diameter at the top portion thereof. The collar portion 11 of the socket is formed to snugly engage the tapered edges of the main body portion to forma securing means of a dovetail cross section, the anged portion 11a, extending from the upper end of the collar portion, engaging the face of the main body portion'.

The bushing structure just .described andv the particular method of forming the engaging walls of the socketwith the internally threaded body portion 12 are more fully described in' my co-pending applications, Serial Nos. 217,031 and 239,207, respectively. However, this particular construction is shown for the purpose of illustrating a preferable form of bushing structure and it will be understood that the plugor bung hereinafter described may be associated with any bushing structure of any container that applicant has knowledge of at the present time..

The plug or bung 14, illustrated in the present embodiment, has a header flange portion 14a, the main body portion adjacent thereto being provided with threads 15 to lengage'the internally "threaded body portion j12. The outer periphery of the flange of thebung 14 ispreferably octagonal in shape and a square recess 16 is formed in the head (for engagement with a tool.

The plug 14 is preferably cast with a peripheral groove 17 beneath the flanged head .portion and adjacent the threads 15, the

groove providing a recess in which a cast material 18 is disposed. YThe cast material results in the formation of a sealing band and may be of lead or of a suitable'material softer` than` the body portion 12 or bung 14. The outer diameter of the sealing band is co-extensive with the outer diameter of the threads of the bung and tapers slightly outwardly from the container at its juncture therewith or, as shown in the drawings, upwardly therefrom.- The threads of the bodyA portion 12 form threads in the cast material in the rethe octagonally shaped h ead portion of the bung, thedepending Vportion being preferably of the same width. A slot or groove 21 is formed in the upper and lower surfaces of the lug preferably at the line of intersection with the plug to form a weakened portion, the use of which will hereinafter be more fully described. -A hole 22 is formed in the plug 19 to receive a pin 23 in snug engagement therewith, the pin 23 being-preferably round, although it is to be understood that any shape or form may be employed as desired.

The depending portion 20 is spaced laterally a `short distance from the collar 11 of the socket to receive therebetween a vertically extending portion 24 of a tag 25. The vertically extending portion 24 has a horizontally extending portion 26 extending in the same direction as the tag proper and from the upper end thereof, the horizontally extending portion 26 being preferably of a widthV to snugly lit in the space between the depending portion 20 and the collarportion of the socket.

In the assembly of the tag 25 with the elements of the bushing construction and the bung, the vertically extending portion 24 is disposed adjacent one of the edges of the poly'gonally shaped socket and the plug 14 is screwed into the container until the depending portion 20 of the lug 19 occupies a position adjacent the vertically extending .portion 24 of the tag 25. L The pin 23 is then inserted in the aperture 22 and is forced downwardly against the horizontally extendthereof. It isusual that the bung and the receiving bushing therefor be positioned adjacent the chime of the barrel and therefore Athe tag has been formed so as to `be capable Leanne of lying in the space between .the bung 14 and the chime 28, the tag conforming to and lying adjacent the curvature thereof although it is to be understood that the body of the tag may assume any position around the periphery of the bushing. As hereinbefore stated, this tag is for the purpose of identifying the contents of the container as for example the different grades of oil. Should the tag 25 be removed anda less expensive oil be substituted for the oil originally conbeen had to the oil since it tained in the container or should an attempt be made to vreplace the tag with another tag,l

strike against one edge of the polygonally shaped socket because of the fact that the edge of the polygonally shaped socket is a'ta'ngent to the circle around which the pin 22 would move. By forcing the pin against the edge ofthe polygonally shaped socket the tangent or edge forms a cam surface vagainst which the pin rides and as it is moved over the cam surface the lug is broken at the weakened portion 21.

Referring now to Figs. 4 and 5 of the drawings, a modified form of this invention is shown in which a socket 11 is formed outwardly from a supporting wall 10 v'of a container-to receive a body portion 12- in snug engagement therewith. As in the preceding construction, the bodyportion 12 is internally threaded to receive an externally threaded bung 14 having a sealing material 18 dis- `posed in a groove 17 beneath the preferably octagonally shaped head portion thereof. A lug 19: having a. depending portion 20 anda weakened portion 21 is likewise preferably formed integrally with the bungll and has an aperture 22 therein to receive a pointed pin 29. The tag 25 has a vertically extending portion 26,*the uppery end of the vertically extending portion being formed to extend horizontally as at 30 in a direction away from the tag proper to engage the outer surface of the flange of the socket. The verticallyy extending portion 26 of the tag 25 preferably vrests against the edge of the. socket 11, the distance between the horizontally extending lportion 30 and the bottom surface of the tag 25 being less than the height of the lsocket 11. Thetag 25 is assembled to this bushing structure in the manner described with reference to Figs. 1 to 3. However, in lieu of the pin deforming the horizontally extending has been in transit portion as provided heretofore, the pointed end portion pierces and projects through the tag proper, the outer diameter of the pointed pin 23 being' preferably spaced from 'the outer edge of the socket 11 just a suicient distance to permit the vertically extending portion26 of the tag to lie therebetween 1n a. clamped relation.

By reason of this ,pin urging the upwardly extendingportion 26 against the socket, d

the main body of the tag 25'will-not give as the pin,29 engages therewith but will permit the pin to pierce therethrough. Thus the tag 25 will not be permitted to be removed by reason of the pin holding the tag, it being y further lnoted that the pin can not be grippe from the top as it is preferably Hush with the top surface of the plug and cannot be forced upwardly from below.

In the previously described embodiment, the pin 23 has been of a size such as to be protected from exterior access by the dependmg portion 20, the pin extending/to within a. short distance from the lower surface and being flush with the top surface thereof. Both the pins of these constructions are preferably of tool-hardened steel so that they cannot'be drilled out of their respective openings.A

Referring now more particularly to Figs.

6 to 10, inclusive, a further modification is shown wherein the supporting wall 10 of the barrel or container has an outwardly extending socket 11 for receiving in snug engagement therewith the internally threaded main body as inthe previously described embodiments. An octagonally shaped bung 14 is adapted to engage the main body portion 12. However, in this instance, the sealing means as shown and described in the previous modilications have been omitted to show the ordinary washer 31 disposed between the flan e of the bung 14 and the outer surface of t e socket 11, flange 19 having a depending portion 20, and a weakened portion 21 formedon the ange of the bung 14, the depending por- Aformed at right angles thereto as at 34. A.

wedge 35 is forced into the space between the depending portion 20 and the vertically extending ortion 33 of the tag 34, the wedge 35 being of) a length to be entlrely enveloped by the lug 19 and the depending Vportion 20 thereof. tends across one end of the` opening into which the wedge 35 is disposed, it is not pos- Inasmuch as the portion 32 ex- 1 sible to release the wedge by any other means than by breaking the extension 32 or by otherwise mutilating the lugl9.

In Fig. 7 itwill be noted that the wedge 35 is of a square cross section and that the wedge in Fig. 9 has a similari cross section with the exception that one edge thereof is tapered to conform to the taper of the collar 1l of the socket and the edge of the main body portion 12. However, it is to be understood that various means may be employed as an obstruction to the travel of the lug 19 whereby a forcing of the plug 14 vbeyond such an obstruction would mutilate the plug such as by the breaking of the luv 19. The wedge 35 maybe of any shapetoconlform withvarious contours of body portions and the like, and hence this application is not to be limited as to the specific construction. Further, the tags 25`and 34 may be formed into Amagious shapes lalthough it is preferable that they be held by the auxiliary means mentioned in this application in addition to the pins and wedges thus described.

'While several embodiments of this invention have been herein shown and described, it is to be understood that various modifications thereof maybe apparent to those skilled in the art without departing from the spirit and scope of this invention, and, therefore, the sameisto be limited only by the prior art and the scope ofthe appended claims.
